The iText API is based on JavaString objects - which represent Unicode characters, so you cann add any text that can be represented in Unicode.
A difficulty may be if the machine where the file is viewed does not have a font with Arabic characters. Unless you can safely assume that it has, it may be better to include a suitable font in the PDF.
